自己治癒セラミックス複合材の有限要素解析

（第2報 酸化反応速度論に基づく発展則の導入）

抄録

In this study, to analyse both damage and healing phenomena of self-healing ceramic materials within the framework of FEM, a novel constitutive model is developed. The damage process is formulated based on a fracture mechanics, while the self-healing process is formulated based on an oxidation kinetics model of self-healing time. Then, we apply the proposed constitutive model to FE analyses of alumina/ SiC nanocomposites materials, in which the unevenness of material properties are considered. The super-healing phenomena of self-healing ceramic matrix composite is demonstrated using proposed FE analysis scheme.
